T 0 all whom t may concern:

Beit known that l, JOSEPH lNGRAM, a citizen of the United States ofAmerica, residing at East Orange, Essex county, State of New Jersey,have invented certain new and useful lmprovements in Motor- CoolingMeans, of which the following is a full, clearfand exact description'.

rlhis invention relates to improvements in cooling means for internalcombustion motors and has for an object to provide means to maintainsuch motors at a relatively low temperature, while in operation, therebypreventing prevaporiz'at-ion of the combustible mixture, which willincrease the power of the motor and also to a. large ertent preventingcarbonization of the pistons and cylinder head, By maintaining a. motorat as low a temperature as possible, lubrication of the motor, that isto say, proper lubrication is possible, high temperature beingnon-conducive to thorough lubrication.

'lo carry my invention into practice, l employ a combination of air anda liquid cooling chemical or compound ot which there are a numberknown-to the art.

ll will now describe my invention in detail, .the novel features otwhich ll will nally claim, reference being had to the ac-v companyingdrawings, wherein Figure l is a diagrammatic View of a motor designed toemploy my improved cooling means;

Fig. 2 is a top lan view thereof, on a.

reduced scale, the a1r collector being shown partly in section;

Fig. 3 is a sectional plan view, the section being on a line 3-3 in Fig.4l;

Fig. d is an enlarged sectional View ot one of the cylinders, thesection being taken on a line t-l in Fig. 1; and

Fig. 5 is a sectional top plan view of one of the cylinders, the sectionbeing taken ona line 5-5 in Fig, 4l.

As herein illustrated, ll have embodied my improvement in a motorcomprised ot four separate cylinders indicated by 6, 7, 8 and 9, but itdesirable a block motor can be emplo ed.` To illustrate my invention, llhave omltted' all reference to valves, push-rods, etc., exce ting inFig. 3, in which one exhaust valpve and its push-rod has been indicated,this being done merely to illustrate one Way of designing the motor.,lin this instance each cylinder is provided with an annular chamber l0to contain a cooling medium, preferably in the form of a'liquidcomposition that will conduct hea-t without retaining same to an extentthat will cause it to become hot. rllhere are a number of suchcompositions known in the arts, and l do vnot limit myself to anyparticular one, but l prefer to use a solution of sodium ammoniiunchlorid. rllhe chamber 10 is provided with an inlet duct 11 for fillingsame, and an out-let duct 12 to dra-w oil the liquid wheneveridesirable.The liquid in the chami ber 10 will absorb 'heat from the adjacent wallof the cylinder and maintain the lower portion of the cylinder cool.Heat absorbed by the liquid in chamber 10 will be absorbed b v the outerwall 12a ont the chamber 10, or at least said outer wall will conductheat from the liquid. Be that as it may, the lower portion of eachcylinder will be kept cool by the liquid or compound in chamber 10: atany rate the liquid in chamber 10 will not circulate.

The upper portion of each cylinder will have applied thereto a. shell 13provided with radial vanes 1d (see Fig. 3). rll`he shell 13 will be inthe nature ot a cup which will be Vslipped over the upper portion of thecylinder, including the cylinder head 15. rllhe vanes lll will beapplied to the head 16 of the shell or cup 13 as well as to thesidewall, as indicated in Fig. d. rllhe head por- `tion ot the shellwill be out out to receive and also torthe reason that ll employ rela-ytively cool air to conduct heat from the vanes, the said vanes will becoparatlvely thin.

@ne of the features ofmy invention is con- 'ning the aiiharound saidvanes in order that the entire radiating surface of `the vanes andportion of the vane shell, intermediate the vanes, will be brought inconj by the exhaust of the motor;

tact with the stream of air as it passes through. To accomplish thisresult, I provide the vane shell with a casing 25. The casing 25 willcompletely encompass the vane shell, as shown in F ig. 4, and whenapplied to an overhead valve motor will also inclose the valves. j

It will be, of course, understood that each cylinder of the motor willbe constructed as described; hence each cylinder will have its ownliquid cooled portion which has no connection with the liquid cooledportion of an adjacent cylinder, but the air cooled portions of thecylinders will be connected, and air caused to circulate therethrough bya medium common to all the cylinders. The air cooled portions of thecylinders are connected by a manifold 26, that is to say, the vane shelleasings 25, at the top thereof, are connected by said manifold 26 whichin turn is connected to the exhaust ipe 21 of the motor by a Siphon-duct28. n short, air is drawn out of the interior of the casings 25 hencecirculation 'through the casings, and around or in contact with thevanes, is produced by the exhaust of the motor. Air which enters thecasings is introduced thereinto adjacent the bottom of the casingsthrough inlet-ducts 29 and 30. The forward end of each vinlet duct 29and 30 is connected to drum 31, the open end 32 of which is directedahead of the motor. The open end of the drum 31 is covered by acollector 33 made up of a frame 34 having partitions 35 lto providesmall channels 36. The drum 31 carries a deflector 37 to direct thecurrentof air toward the ducts 29 and 30. lIn other words,

the deflector 37 divides the current of air.y

As can be seen, the drum 31 is made up of angular"walls all directedtoward the ducts 29 and 30. When the motor is in operation, the exhaustwill by siphonic action induce a flowof air'through the air casings 25.It will, of course, be'evident that air will be drawn into drum 31,through the collector 33; thence through ducts 29 and 30 into the lowerportion of the'air-casings 25'; thence upwardly between the vanes 14into'upper lportion of the air casings; thenceinto theairexhaustmanifold 26 and out through the siphon duct 28 into theexhaust pipe.

The circulation of cool vair through the air casings is effectedentirely by the exhaust of ther motor. To sum up, I have constructed amotor having the firing chambers of the cylinders air cooled, and theremainder of the cylinders liquid cooled.

In Fig. 1, I haveillustrated an -intake manifold 38 merely to add to theappearance of the motor. In this instance, the shell 13 is connected tothe'upper wall, 39 of the liquid chamber 10 by bolts 30 and the outercasing 25 tothe flange 41 of shell 13 by bolts 42 Having described myinvention, what Il claim and desire to secure by Letters Patent is 1.
